Dear London, I do love you but you still don't do a great job of accommodating those who are less-than-fully-able-bodied. (Also, my feet are swollen by the end of the day, dammit. I have to walk a minimum of 5 km on my commute and I weigh 14 kg more than I normally do. And yes, I am wearing sensible shoes.)
